  • Glucose
  • Oxygen
• What are the differences between photosynthesis and respiration?

  Photosynthesis:

  • Produces glucose and oxygen
  • Requires light energy
  • Occurs in chloroplasts

  
  

  Respiration:

  • Consumes glucose and oxygen
  • Releases carbon dioxide and water
  • Occurs in mitochondria
